High pressure aloft will build across the Gulf South and that means our temperatures are going up! Highs will be climbing into the mid and even upper 90s for some of us. Rain chances will also go down.

OUTSIDE High pressure is in the Gulf, and you can very clearly see the clockwise flow around the high sending in warm moist air. What a difference from last week when we had a weak cold front in the area helping to dry out the air. Today's rain has basically dissipated. We had an area of disturbed weather moving to the east that caused some rain and storms to fire up over Southwest Mississippi. Daytime heating and moisture caused storms to fire up on the South Shore. There is an upper level high over Eastern Florida. The clockwise flow shows up well on the water vapor imagery. That upper high is going to move west beginning tomorrow. High pressure aloft causes the air to basically sink or be compressed. Sinking air causes things to heat up. Keep in mind at the surface we are still going to have an onshore flow. That means there is going to be plenty of moisture in place. The message is...it's going to be hot and humid. The heat index is going to be around 105 and higher by Mid week. Also when the air is sinking...it's hard to get air rising. You need rising air in order for clouds to form and rain to develop. We will have lower rain chances through the week. We did not have a lot of rain today. The highest rainfall amount was in Hammond. .75" was reported. Got some great twitpics in of iridescence. That occurs when the sunlight is bent by water droplets of uniform size. Basically you get colors of the rainbow ...it can happen with moonlight too. Highs today were in the low to mid 90s. Right now we are in the mid 70s to low 80s. The humidity is high. The heat index is still near 90 at the Lakefront. Lows will be in the mid to upper 70s. Highs will be in the low to mid 90s Tuesday, but higher going into Wednesday. We will see more mid 90s and some upper 90s going into the week. The heat index will be over 105 for many of us. We are watching two areas of disturbed weather in the Central Atlantic. Both have a low chance for tropical development. In the Gulf of Mexico we have an upper level low. That is not conducive to development. In the Pacific we are watching the 12th strom of the Season. Lowell has formed. Winds are 40 mph. Karina is stronger with 65 mph winds. These storms are well out to sea. MYRTLE BEACH PELICANS MANAGER TIRADE...
